When developing a sales comparison approach under USPAP, what must the appraiser do?

In the context of developing a sales comparison approach under USPAP (Uniform Standards of Professional Appraisal Practice), it is essential for the appraiser to analyze all relevant data available to arrive at a coherent value conclusion. This process involves gathering information about comparable properties that have recently sold, as well as assessing their qualities and differences in relation to the subject property.

Analyzing available data helps the appraiser develop insights about market trends, comparable property features, and any factors that may influence value, such as location and condition. This comprehensive analysis ensures that the final opinion of value is supported by robust evidence and aligns with market realities. Thus, this approach reflects the diligent and thorough nature that is required in professional appraisal work. This is fundamental not only for adhering to USPAP but also for maintaining the credibility of the appraisal in whatever context it is being used, be it for financing, taxation, or any other purpose.

The other options, while relevant to the appraisal process, do not capture the essence of analyzing available data as the foundational step in reaching a value conclusion. For instance, using required methods and techniques or adhering to guidelines regarding time and distance play a role in appraisal practice, but they are more about procedural adherence rather than the fundamental analytical requirement at the outset
